Autofocus threat indicator timestamp does not tally with Minemeld logs

Hi all,

Got a question regards to the time stamp seen on Minemeld logs then I mine samples from autofocus.

Take for example, from AF-Ransomware Node in mine meld, I can see a particular hash having a "first seen" and "last seen" with a format of "1531114747953", however, when I search the SHA 256 hash using Autofocus search feature, the "Created" and "Finished date" does not seems to tally.

I have 2 question,

1. how do I read the format of "1531114747953"?

2. why doen't this timestamp tally with Autofocus?

See my below screen capture for example, thanks!

Hi @chtoh82,

the timestamps in MM are Unix timestamps in milliseconds (basically milliseconds since epoch), UTC TZ.

First_seen and last_seen reflect the first and last time that indicator was provided by the AF API, not the timestamps of the sample as most of the times indicators are related to multiple samples.
